we are supposed to
- Add a rule to run incremental assembly on containers in case there are
    multiple volumes in a container and we only started some of them in the
    initramfs
- Make -If work with imsm arrays. We had too restrictive of a test in
    sysfs_unique_holder.
- Make incremental assembly of containers act like incremental assembly of
    regular devices (aka, --run is needed to start a degraded array)
